Curing Resin

COMPOSITION

• This is heat reactive butyl curing octyl phenol formaldehyde resin. Ex. FINOREX PB 1045.
• Adhesive Resin: Ex. FINOREX PB 518, PB 154 , PB 212, PB 110
• Methylol and Dibenzyl ethers  form  Quinone Methide QM intermediate.
• QM reacts with olefines in rubber to form carbon carbon  bond

PURPOSE

• It is used in combination with halogen  like chloroprene rubber and zinc oxide and  yields butyl vulcanizates . High heat stability  in bladder
• Methylol content in resin determines   modulus values.
• Used in various adhesives

APPLICATION

Tire Curing Bladders, Conveyor Belts, Gaskets, Adhesives
